PROBLEM TO BE SOLVED: To provide a temperature measuring device that is able to accurately measure the temperature of a medium in a pipe by means of a configuration set outside the pipe.SOLUTION: A temperature measuring device comprises: a transmitting section 21 that transmits an electric signal for generating an ultrasonic signal, to an ultrasonic probe 10a; a reception section 22 that receives an electric signal in an ultrasonic signal made incident on an ultrasonic probe 10b; a time measuring section 23 that calculates, on the basis of the electric signal received by the reception section 22, a first propagation time by first propagation, which is taken for an ultrasonic signal transmitted from the ultrasonic probe 10a to pass through a medium 102 and be received by the ultrasonic probe 10b, and a second propagation time by second propagation in which an ultrasonic signal propagates by reflecting in a pipe 100 by one or more times than the first propagation; and a temperature calculating section 24 that calculates a temperature of the medium 102 on the basis of a difference between the first propagation time and the second propagation time.SELECTED DRAWING: Figure 1 【課題】配管外に設置される構成で、配管内の媒体の温度を精度良く計測することができる温度計測装置を提供すること。【解決手段】超音波探触子１０ａに対して超音波信号を発生させる電気信号を送信する送信部２１と、超音波探触子１０ｂに入射した超音波信号の電気信号を受信する受信部２２と、受信部２２が受信した電気信号をもとに、超音波探触子１０ａから送信された超音波信号が媒体１０２内を通過して超音波探触子１０ｂで受信するまでの第１の伝搬による第１の伝搬時間と、超音波信号が前記第１の伝搬よりも配管１００内を１回以上多く反射して伝搬する第２の伝搬による第２の伝搬時間とを算出する時間計測部２３と、前記第１の伝搬時間と前記第２の伝搬時間との差をもとに媒体１０２の温度を演算する温度演算部２４と、を備える。【選択図】図１
